Abstract:To achieve precise control of load frequency in new power systems and effectively address the challenges of nonlinearity, randomness, and uncertainty caused by the integration of large-scale renewable energy, an Actor-Critic deep reinforcement learning algorithm based on radial basis function (RBF) network is adopted to construct an load frequency control (LFC) strategy with adaptive proportional-integral-derivative (PID) control. First, the stable control structure of the power system and the dilemmas faced by LFC are analyzed. The advantages of intelligent control strategies are expounded, and modeling is completed, followed by the design of an adaptive optimization system. Through Matlab simulation, the controller is compared and analyzed with the particle swarm optimization (PSO)-tuned controller. The results show that the proposed controller significantly reduces the four error parameters of area control error (ACE) in the two areas, demonstrates stronger performance in minimizing ACE and reducing deviations, effectively improves the adaptability and robustness of LFC, and provides a new method with both theoretical and engineering values for the construction of new power systems.
